*melanin: the pigment produced by your skin that gives it a tanned colour. 2. Take your time, and build your tan up slowly. Everyone reacts differently to the sun, but here are some guidelines to get you started: If tanning in the sun, start with only 15-20 minutes in the sun on your first session.
